I have 2 babies and got pregnant instantly..

What is wrong with me now? I have been trying for a 3rd for a year and nothing! My doctor is talking clomid thank God! I have been diagnosed with endomyosis as well. Not endometriosis but endomyosis. My mother and grandmother both had to have hysterectomys because of it in their earlier 30’s and I am 31 almost I am scared. I want at least one more baby! Anyone have a same situation? My appt is feb 24th to start the clomid process.
